Table: Mosquito Check Survey (Page 73)

Location	Stagnant Water (✓)
Pot	✓
Cooler
Tank
Any open space in the school ground	✓
Gutter	✓
Any other place (pond near school)	✓

Since how many days has water collected there?

About one week in the pot and pond; three days in the gutter and open space (based on page 74).

Who is responsible for keeping these places clean?

School staff for pots and coolers; municipal authorities for gutters and open spaces (inferred, page 73).

Who is supposed to get the gutters and drains repaired?

Municipal authorities (inferred, page 73).

Can any larvae be seen in the collected water?

Yes, larvae were seen in the pot and pond (page 74).

Has it caused any problem in the area?

Yes, increased mosquitoes causing health risks (page 74).

This table (page 73) records a mosquito check survey. Stagnant water was found in a pot, open space, gutter, and nearby pond, consistent with Group 2’s findings (page 74). Larvae in the pot and pond increase mosquito populations, posing health risks. Municipal authorities and school staff are typically responsible for cleaning and repairs (inferred, page 73).
